CROSS-REFERENCE TO RELATED APPLICATION

This application claims the priority benefit of Korean Patent Application No. 10-2016-0147224, filed on Nov. 7, 2016 in the Korean Intellectual Property Office, the content of which is incorporated by reference herein in its entirety.

TECHNICAL FIELD

The present application generally relates to a vehicle and a control method thereof.

BACKGROUND

A vehicle is an apparatus that moves in a direction desired by a user riding therein. A representative example of a vehicle may be an automobile.

In some implementations, a variety of sensors and electronic devices have been mounted in vehicles for the convenience of a user who uses the vehicle. In particular, for user driving convenience, an Advanced Driver Assistance System (ADAS) has been actively studied. In addition, enormous efforts have been being made to develop autonomous vehicles.

If a user applies a command through a handle or an accelerator pedal when a vehicle is travelling autonomously, the vehicle basically ignores the user command and keeps travelling autonomously.

However, it is sometimes necessary to apply a user's command even when the vehicle is travelling autonomously. In addition, if the user fails to perceive a dangerous situation, which is recognized by the vehicle, and inputs a wrong command, it is safe that the vehicle ignores the user's command and keeps travelling autonomously.

For these reasons, there are ongoing efforts to study a technology that applies a user command, which is received during autonomous travelling of a vehicle, only when the user command is suitable for a driving situation of the vehicle.

DETAILED DESCRIPTION

A vehicle as described in this specification can include an automobile and a motorcycle. A vehicle as described in this specification may include all of an internal combustion engine vehicle including an engine as a power source, a hybrid vehicle including both an engine and an electric motor as a power source, and an electric vehicle including an electric motor as a power source.

FIG. 1 illustrates an example vehicle. FIG. 2 illustrates an example exterior of a vehicle. FIGS. 3 and 4 illustrate an example interior of a vehicle. FIGS. 5 and 6 illustrate one or more example objects outside a vehicle. FIG. 7 illustrates an example vehicle.

Referring to FIGS. 1 to 7, a vehicle 100 may include a plurality of wheels, which are rotated by a power source, and a steering input device 510 for controlling a driving direction of the vehicle 100.

The vehicle 100 may be an autonomous vehicle.

The vehicle 100 may travel autonomously under the control of the controller 170.

The vehicle 100 may travel autonomously based on vehicle driving information.

The vehicle driving information may be information that is acquired by various units during travelling of the vehicle 100.

The vehicle driving information may include at least one of the following: information on an object outside the vehicle, which is acquired by the object detection device; information received using the communication device 400 while the vehicle 100 travels; navigation information; control status information of the vehicle 100, and location information of the vehicle 100. For example, the vehicle driving information may include information on a different vehicle, which is transmitted by the different vehicle, information on a route of the vehicle 100, and map information.

For example, the vehicle driving information may indicate: a type, location, movement of an object located around the vehicle 100; whether a traffic line exists in the vicinity of the vehicle 100; whether any nearby vehicle is travelling while the vehicle 100 is stopped; whether there is a space in the vicinity of the vehicle 100 to stop; whether a vehicle and an object could collide; where a pedestrian or a bicycle is located with reference to the vehicle 100; a type of a roadway in which the vehicle 100 is travelling, a status of a traffic light in the vicinity of the vehicle 100, and movement of the vehicle 100.

The vehicle driving information may be acquired by at least one of an object detection device 300, a communication device 400, a navigation system 770, a sensing unit 120, and an interface 130, and provided to a controller 170. Based on the vehicle driving information, the controller 170 may control the vehicle 100 to travel autonomously.

A control mode of the vehicle 100 may be a mode indicating of which subject controls the vehicle 100. For example, the control mode of the vehicle 100 may include: an autonomous vehicle in which the control unit 170 or the operation system included in the vehicle controls the vehicle 100; a manual driving mode in which a driver in the vehicle 100 controls the vehicle 100; and a remote control mode in which a device other than the vehicle 100 controls the vehicle 100.

When the vehicle 100 is in the autonomous mode, the controller 170 or the operation system 700 may control the vehicle 100 based on vehicle driving information. Accordingly, the vehicle 100 may travel without a user command received using the driving manipulation device 500. For example, the vehicle 100 in the autonomous mode may travel based on information, data, or a signal that is generated in a driving system 710, a parking-out system 740, and a parking system 750.

If a user command is received using the driving manipulation device 500 while the vehicle 100 travels autonomously, the vehicle may determine whether the user command is inconsistent with acquired vehicle driving information.

If the user command is inconsistent with the vehicle driving information, the vehicle 100 may ignore the user command. If the user command is consistent with the vehicle driving information, the vehicle 100 may apply the user command.

If the vehicle 100 applies the user command, the vehicle 100 may travel based on the user command and the vehicle driving information. If the vehicle 100 ignores the user command, the vehicle 100 may travel based solely on the vehicle driving information. Detailed description thereof will be provided with reference to FIG. 8 and other following drawings.

When the vehicle 100 in the manual driving mode, the vehicle 100 may be controlled by a user command received using the driving manipulation device 500, the user command which is with regard to at least one of steering, acceleration, and deceleration. In this case, the driving manipulation device 500 generates an input signal corresponding to the user command, and provide the generated input signal to the controller 170. The controller may control the vehicle based on the input signal provided by the driving manipulation device 500.

When the vehicle 100 in the remote control mode, a device other than the vehicle 100 may control the vehicle 100. If the vehicle 100 operates in the remote control mode, the vehicle 100 may receive a remote control signal, transmitted by a different vehicle, via the communication device 400. The vehicle 100 may be controlled based on the remote control signal.

Based on a user input received using the user interface device 200, the vehicle 100 may enter one of the autonomous mode, the manual driving mode, and the remote control mode. A control mode of the vehicle may be switched to one of the autonomous mode, the manual driving mode, and the remote control mode based on at least one of driver state information, vehicle driving information, and vehicle state information.

The driver state information may be generated based on an image or biometric information of a driver detected by an internal camera 220 or a biometric sensor 230. For example, the driver state information may be information that is generated based on an image, acquired by the internal camera 220, about an eye gaze, a face, a behavior, a facial expression, and a location of the driver. For example, the driver state information may be information generated based on biometric information of a user acquired by the biometric sensing unit 230.

For example, the driver state information may indicate a direction in which a gaze of the driver is directed, whether the driver is dozing off, a health condition of the driver, and an emotional condition of the driver.

The driver state information may be generated through the user interface device 200, and provided to the controller 170.

The vehicle state information may be information about the states of various units provided in the vehicle 100. For example, the vehicle state information may include information about the operational states of the user interface device 200, the object detection device 300, the communication device 400, the driving manipulation device 500, the vehicle drive device 600, and the operation system 700, and information about an error of each unit.

For example, the vehicle state information may indicate: whether a GPS signal of the vehicle 100 is received normally; whether an error has occurred in at least one sensor provided in the vehicle 100, and whether each device provided in the vehicle 100 operates normally.

For example, the control mode of the vehicle 100 may be switched from a manual driving mode to an autonomous mode, or vice versa, based on object information generated by the object detection device 300.

For example, the control mode of the vehicle 100 may be switched from a manual driving mode to an autonomous mode, or vice versa, based on information received using the communication device 400.

In some implementations, the term “overall length” means the length from the front end to the rear end of the vehicle 100, the term “overall width” means the width of the vehicle 100, and the term “overall height” means the height from the bottom of the wheel to the roof. In the following description, the term “overall length direction L” may mean the reference direction for the measurement of the overall length of the vehicle 100, the term “overall width direction W” may mean the reference direction for the measurement of the overall width of the vehicle 100, and the term “overall height direction H” may mean the reference direction for the measurement of the overall height of the vehicle 100.

Specifically, the controller 170 may determine, based on vehicle driving information, a change in a probability for the vehicle 100 to collide with the object, the change in the probability which is expected when the vehicle 100 travels based on a user command. For example, if a probability of collision between the vehicle 100 and an object is 10% in the current situation and expected to increase to 80% when the vehicle 100 travels based on a user command, the controller 170 may determine that the user command is inconsistent with vehicle driving information.

For example, if it is determined that traveling of the vehicle 100 based on a user command will increase impact impulse of collision between the vehicle 100 and an object, the controller 170 may determine that the user command is inconsistent with vehicle driving information. If it is determined, based on the vehicle driving information, that the vehicle 100 is unable to avoid the collision with the object, the controller 170 may control the vehicle 100 to reduce the impact impulse from the collision. For example, if it is determined that the vehicle 100 is unable to avoid an object approaching from the side of the vehicle 100, the controller 170 may control the vehicle 100 so that the object collides with a part of the front or rear of the vehicle 100. As a result, the vehicle 100 would spin after the collision, so the impact impulse transferred to the vehicle 100 may be reduced. In addition, at a time when the vehicle 100 collides with an object, the controller 170 may control the vehicle 100 to move in a direction corresponding to a direction of the object so as to reduce impact impulse transferred to the vehicle 100. When the vehicle 100 collides with an object, impact impulse transferred to the vehicle 100 moving under control of the controller 170 may be relatively less than impact impulse transferred to the vehicle 100 moving based on a user command.

For example, if it is determined that travelling of the vehicle 100 based on a user command is expected to increase impact impulse transferred to an occupant in a collision between the vehicle 100 and an object, the controller 170 may determine that the user command is inconsistent with vehicle driving information. The controller 170 may determine a location of an occupant based on driver state information. By considering the location of the occupant and a direction in which the vehicle 100 will collide with the object, the controller 170 may determine impact impulse that is expected to be transferred to the occupant in the collision between the vehicle 100 and the object.

For example, if it is determined that driving the vehicle 100 based on a user command will result in violation of a traffic regulation, the controller 170 may determine that the user command is inconsistent with vehicle driving information. For example, the violation of the traffic regulation may include crossing the centerline, changing a traffic lane in a lane change-prohibited zone, entering a specific vehicle-dedicated road into which entrance is prohibited, straying from a driveway, driving while disobeying a traffic sign, and violating a traffic signal. When the vehicle 100 is travelling based on a user command, the controller 170 may determine, based on vehicle driving information, whether the vehicle 100 violates a traffic regulation. For example, if a user command for acceleration is received in a case where the current speed of the vehicle 100 is 80 km/h and a speed limit on a road on which the vehicle 100 is travelling is 80 km/h, the controller 170 may determine that the user command is inconsistent with vehicle driving information.

For example, if it is determined that driving the vehicle 100 based on a user command will render the vehicle 100 out of control, the controller 170 may determine that the user command is inconsistent with vehicle driving information. For example, an out-of-control state may include slipping to the point where the vehicle 100 is uncontrollable, falling down from a cliff, and occurrence of an understeering or oversteering sensation. For example, based on vehicle driving information, the controller 170 may determine a state of a road surface on which the vehicle 100 is travelling, a speed of the vehicle 100, and the maximum steering angle which does not cause the vehicle 100 to slip. If a steering angle corresponding to a received user command is greater than the determined maximum steering angle in a case where ice is present on the road and a speed of the vehicle 100 is 80 km/h, the controller 170 may determine that the user command is inconsistent with vehicle driving information.

For example, if travelling of the vehicle 100 based on a user command will lead the vehicle 100 to stray from a set path during an automatic parking operation, the controller 170 may determine that the user command is inconsistent with vehicle driving information. For automatic parking of the vehicle 100, the controller 170 may set a parking path along which the vehicle 100 is to be parked. If it is determined that the vehicle 100 will not stray from the set parking path even when a received user command is applied, the controller 170 may apply the user command for the automatic parking operation. For example, if a user command for acceleration is received during an automatic parking operation of the vehicle 100, the controller 170 may increase a speed of the vehicle 100 as long as the vehicle 100 does not stray from a set parking path.

In response to determination to apply the user command, the controller 170 may control the vehicle 100 based on the user command and the vehicle driving information in 5400.

The controller 170 may control the vehicle 100 based on a user command and a vehicle driving command, so that a driver's intention may be reflected in driving the vehicle 100.

In response to determination to ignore the user command, the controller 170 may control the vehicle 100 based solely on vehicle driving information in S100.

FIG. 9 is a flowchart illustrating another example method for controlling an autonomous vehicle.

When the vehicle 100 is in an autonomous mode, the controller 170 may control the vehicle 100 based on vehicle driving information, which is acquired from various units provided in the vehicle 100, so that the vehicle 100 can travel autonomously in 5100. The controller 170 may acquire driver state information from the occupant sensing unit 240 during autonomous travelling of the vehicle 100 in S100.

The driver state information may include a driver's image or biometric information detected using the internal camera 220 or the biometric detection unit 230. For example, the driver state information may be information that is generated based on an image acquired using the internal camera 220, the image which is about a driver's gaze, face, behavior, facial expression, and location. For example, the driver state information may be information that is acquired using the biometric sensor 230, the information which is about a user's biometric information. For example, the driver state information may indicate a direction in which a gaze of a driver is directed, whether the driver is dozing off, a health condition of the driver, and an emotional state of the driver.

The controller 170 may determine whether a user command is received through an input device during autonomous travelling of the vehicle 100 in S200.

If the user command is received, the controller 170 may determine, based on driver state information, whether the user command is intended by a driver in S310.

For example, if it is determined, based on driver state information, that the driver inputs a user command while looking ahead, the controller 170 may determine that the user command is intended by the driver. For example, if it is determined, based on driver state information, that the driver is dozing off at a time when a user command is received, the controller 170 may determine that the user command is not intended by the driver.

If it is determined that a user command is not intended by the driver, the controller 170 may determine to ignore the user command, and therefore, the controller 170 may control the vehicle based solely on vehicle driving information in S100.

If it is determined that the user command is intended by the driver, the controller 170 may determine whether the user command is inconsistent with the vehicle driving information in S320.

If it is determined that the user command is consistent with the vehicle driving information, the controller 170 may control the vehicle based on the user command and the vehicle driving information in S400.

If it is determined that the user command is inconsistent with the vehicle driving information, the controller 170 may control the vehicle 100 based solely on the vehicle driving information in S100.

FIGS. 10A to 10F illustrate an example method of controlling an autonomous vehicle.

Referring to FIG. 10A, if it is determined that driving the vehicle 100 based on a user command will lead the vehicle 100 to cross the centerline, the controller 170 may determine that the user command is inconsistent with vehicle driving information.

Based on the vehicle driving information, the controller 170 may determine a location of the centerline, a location of the vehicle 100, and a distance between the centerline and the vehicle 100.

If a user command for turning a steering direction toward the centerline is received when the vehicle 100 is travelling in a lane right next to the centerline, the controller 170 may determine that the user command is inconsistent with vehicle driving information, and therefore, the controller 170 may determine to ignore the user command. The controller 170 may control the vehicle 100 based solely on the vehicle driving information. In this case, a steering direction of the vehicle 100 which is now travelling may not be changed.

Referring to FIG. 10B, if it is determined that driving the vehicle 100 based on a user command will lead the vehicle 100 to collide with a nearby, the controller 170 may determine that the user command is inconsistent with vehicle driving information.

If a user command for acceleration and a user command for steering are received through the driving manipulation device 500, the controller 170 may determine that each of the two user commands is inconsistent with vehicle driving information.

If it is determined, based on vehicle driving information, that a nearby vehicle 102a exists within a safety distance ahead of the vehicle 100, the controller 170 may determine that a user command for acceleration is inconsistent with the vehicle driving information. In this case, if the vehicle 100 accelerates, a probability to collide with the nearby vehicle 102 a will increase. Thus, the controller 170 may ignore the user command for acceleration and control the vehicle 100 based solely on the vehicle driving information.

If it is determined, based on vehicle driving information, that a nearby vehicle 102 b exists in a lane next to the vehicle 100, the controller 170 may determine that a user command for turning a steering direction toward the nearby vehicle 102 b is inconsistent with the vehicle driving information. In this case, if the steering direction of the vehicle 100 is changed based on the user command, the vehicle 100 may collide with the nearby vehicle 102. Thus, the controller 170 may ignore the user command for steering and control the vehicle 100 based solely on the vehicle driving information.

A nearby vehicle 102 c exists in a safety distance behind the vehicle 100, and thus, the controller 170 may ignore the user command although a user command for deceleration is received.

Referring to FIG. 10C, if it is determined that driving the vehicle 100 based on a user command will render the vehicle 100 to be out of control, the controller 170 may determine that the user command is inconsistent with vehicle driving information.

Based on a front camera image included in the vehicle driving information, the controller 170 may determine whether an icy road 103 is present ahead of the vehicle 100.

If a steering direction of the vehicle 100 is changed based on a user command for steering when the vehicle 100 enters the icy road 103, the controller 170 may determine that the vehicle 100 will slip and go out of control.

The controller 170 may determine that the user command for steering, which is received at a time when the vehicle 100 enters the icy road 103, is inconsistent with the vehicle driving information. Based on this determination, the controller 170 may ignore the user command.

The controller 170 may ignore the user command and control the vehicle 100 based solely on the vehicle driving information. Accordingly, when entering the icy road 103, the vehicle 100 may travel without turning its steering direction.

Referring to FIG. 10D, if it is determined that driving the vehicle 100 based on a user command will result in violation of a traffic regulation, the controller 170 may determine that the user command is inconsistent with vehicle driving information.

Based on traffic sign information included in the vehicle driving information, the controller 170 may recognize that a speed limit is 60 km/h on a roadway on which the vehicle 100 is travelling.

In the example (a), if a user command for acceleration is received while it is determined, based on vehicle driving information, that the vehicle 100 is travelling at 60 km/h, the controller 170 may determine that the user command is inconsistent with the vehicle driving information. In this case, if the vehicle 100 applies the user command for acceleration, the vehicle 100 may violate the speed limit. Thus, the controller 170 may determine that the user command is inconsistent with the vehicle driving information.

The controller 170 may ignore the user command and control the vehicle 100 based solely on the vehicle driving information. In this case, the vehicle 100 may travel without acceleration.

In the example (b), if a user command for acceleration is received while it is determined, based on vehicle driving information, that the vehicle 100 is travelling at 40 km/h, the controller 170 may determine that the user command is consistent with the vehicle driving information. The vehicle 100 is able to accelerate up to the speed limit, and therefore, the controller 170 may determine that the user command is consistent with the vehicle driving information.

The controller 170 may apply a user command for acceleration. The controller 170 may control the vehicle 100 based on the user command and the vehicle driving information. Accordingly, the controller 170 may control the vehicle 100 to accelerate up to the speed limit based on the user command.

Referring to FIG. 10E, if it is determined that driving the vehicle 100 based on a user command will lead the vehicle 100 to collide with a nearby vehicle 105 b, the controller 170 may determine that the user command is inconsistent with vehicle travelling information.

If a driver fails to recognize the presence of a heavy truck 105 b when the vehicle 100 possibly collides with the nearby vehicle 105 a, the driver may input a user command for turning a steering direction to the left in order to avoid collision with the nearby vehicle 105 a. If the vehicle 100 applies the user command for turning a steering direction to the left, the vehicle 100 may collide with the heavy truck 105 b.

The controller 170 may recognize the heavy truck 105 b based on information provided by the communication device 400 or the object detection device 300, the information which is included in vehicle driving information. Based on the vehicle driving information, the controller 170 may determine that the vehicle 100 needs to turn its steering direction to the right.

The controller 170 may determine that the user command is inconsistent with the vehicle driving information, because a steering direction corresponding to the user command is different from a steering direction determined based on the vehicle driving information. The controller 170 may ignore the user command and control the vehicle 100 based solely on the vehicle driving information. The controller 170 may control the vehicle 100 to turn a steering direction to the right. Accordingly, the vehicle 100 may be able to avoid the collision with any of the nearby vehicle 105 a and the heavy truck 105 b.

Referring to FIG. 10F, if it is determined that driving the vehicle 100 based on a user command will result in violation of a traffic signal, the controller 170 may determine that the user command is inconsistent with vehicle driving information.

Based on an image of the traffic light 106 b detected using the object detection device 300 or based on signal information of the traffic light 106 b received using the communication device 400, the controller 170 may determine a signal of a traffic light 106 b ahead of the vehicle 100. The vehicle driving information may include the image of the traffic light 106 b detected using the object detection device 300 or signal information of the traffic light 106 b received using the communication device 400.

In the example (a), if a user command for acceleration is received and it is determined that a signal of the traffic light 106 b is green, the vehicle 100 may not violate the traffic signal even when travelling based on the user command. Thus, the controller 170 may determine that the user command is consistent with the vehicle driving information.

The controller 170 may accelerate the vehicle 100 by applying the user command.

In the example (b), if a user command for acceleration is received while it is determined that a signal of the traffic light 106 b is red, the vehicle 100 may violate the signal when travelling based on the user command. Thus, the controller 170 may determine that the user command is inconsistent with vehicle driving information.

The controller 170 may ignore the user command and control the vehicle 100 based solely on the vehicle driving information.

FIG. 11 illustrates example user input that is not intended by a driver.

Referring to the example (a) in FIG. 11, the controller 170 may determine whether a driver is dozing off, based on the driver's image acquired by the internal camera 220.

If it is determined that the driver is dozing off, the controller 170 may determine that a user command is not intended by the driver. In this case, the controller 170 may ignore a user command although the user command is consistent with vehicle driving information. Thus, the controller 170 may control the vehicle 100 based solely on the vehicle driving information.

Referring to the example (b) in FIG. 11, the controller 170 may determine whether a driver is looking ahead, based on the driver's image acquired by the internal camera 220.

If a user command is received while it is determined that the driver is not looking ahead, the controller 170 may determine that the received user command is not intended by the driver. In this case, the controller 170 may ignore the user command although the user command is consistent with vehicle driving information. Thus, the controller 170 may control the vehicle 100 based solely on the vehicle driving information.

FIG. 12 is a flowchart illustrating an example method for controlling an autonomous vehicle based on one or more user commands.

When the vehicle 100 is in an autonomous mode, the controller 170 may control the vehicle 100 based on vehicle driving information acquired by various units provided in the vehicle 100, so that the vehicle 100 is able to travel autonomously in S100.

The controller 170 may determine whether at least one of a user command for steering, a user command for acceleration, and a user command for deceleration is received using the driving manipulation device 500 in S200.

The user command for steering may be a user command received through a steering input device. The user command for steering may be a command to turn a steering direction of the vehicle 100. The user command with regard to acceleration may be a user command received through an acceleration input device. The user command for acceleration may be a command to increase a speed of the vehicle 100. The user command for acceleration may be a user command received through a brake input device. The user command for deceleration may be a command to reduce a speed of the vehicle 100.

The controller 170 may determine whether to apply one or more user commands, received using the driving manipulation device 500, individually in S330.

If a user command for steering is received through the driving manipulation device 400 in S210, the controller 170 may determine whether to apply the user command in S310. If it is determined, based on vehicle driving information, that driving the vehicle 100 based on the user command for steering will increase a probability of collision with an object, increase impact impulse from the collision with the object, result in violation of a traffic regulation, or render the vehicle 100 out of control, the controller 170 may determine to ignore the user command for steering. In other cases, the controller 170 may determine to apply the user command for steering.

In response to determination to apply the user command for steering, the controller 170 may control the vehicle based on the user command and vehicle driving information in S410. The controller 170 may turn a steering direction of the vehicle 100 based on the user command and the vehicle driving information.

When a user command for acceleration is received through the driving manipulation device 500 in S220, the controller 170 may determine whether to apply the user command in S320. If it is determined, based on vehicle driving information, that increasing a speed of the vehicle 100 based on the user command will increase a probability of collision with an object, increase impact impulse from the collision with the object, result in violation of a traffic regulation, or render the vehicle 100 out of control, the controller 170 may determine to ignore the user command. In other cases, the controller 170 may determine to apply the user command for acceleration.

In response to determination to apply the user command for acceleration, the controller 170 may control the vehicle 100 based on the user command and the vehicle driving information in S420. The controller 170 may increase a speed of the vehicle 100 based on the user command and the vehicle driving information.

When a user command for deceleration is received through the driving manipulation device 500 in S230, the controller 170 may determine whether to apply the user command for deceleration in S330. If it is determined, based on vehicle driving information, that reducing a speed of the vehicle 100 based on the user command for deceleration will increase a possibility of collision with an object, increase impact impulse from the collision with the object, result in violation of a traffic regulation, or render the vehicle 100 out of control, the controller 170 may determine to ignore the user command. In other cases, the controller 170 may determine to apply the user command for deceleration.

In response to determination to apply the user command for deceleration, the controller 170 may control the vehicle 100 based on the user command and the vehicle driving information in S430. The controller 170 may reduce a speed of the vehicle 100 based on the user command and the vehicle driving information.

FIG. 13 illustrates an example autonomous vehicle that autonomously ravels based on at least one user input.

While the vehicle 100 travels autonomously, the controller 170 may receive a user command for acceleration and a user command for steering.

When it is determined, based on vehicle driving information, that a nearby vehicle 120a exists within a safety distance ahead of the vehicle 100, the controller 170 may determine that the user command for acceleration is inconsistent with vehicle driving information. In this case, if the vehicle 100 accelerates based on the user command, a possibility to collide with the nearby vehicle 120a will increase. Thus, the controller 170 may determine to ignore the user command for acceleration. The controller 170 may ignore the user command for acceleration and control the vehicle 100 based on the vehicle driving information.

The controller 170 may receive a user command for turning a steering direction of the vehicle 100 to the right. When it is determined, based on vehicle driving information, that the centerline or an object does not exist on the right side of the vehicle 100, the controller 170 may determine that the user command for steering is consistent with the vehicle driving information. In this case, even when the vehicle 100 turns its steering direction to the right based on the user command, the vehicle 100 may not collide the object, violate a traffic regulation, or go out of control. Thus, the controller 170 may determine to apply the user command for steering. Accordingly, the controller 170 may control the vehicle 100 based on the user command for steering and the vehicle driving information. The vehicle 100 may move rightward based on the user command and the vehicle driving information.

If a user command is applied, the controller 170 may apply all or some of control quantity corresponding to the user command.

A control quantity corresponding to a user command may indicate a specific steering angle or speed variation which corresponds to the user command. For example, if a driver rotates a steering wheel at a specific angle to the right, the control quantity corresponding to a user command may be an angle at which a steering direction of the vehicle 100 is to be turned. For example, if a driver presses an accelerator pedal to a specific depth, a control quantity corresponding to a user command may be an amount of acceleration of the vehicle 100.

In addition, in response to determination to apply a user command, the controller 170 may apply a preset control quantity corresponding to the user command. For example, when applying a user command for turning a steering direction to the right, the controller 170 may control the vehicle 100 to move into the right-hand lane, regardless of an angle corresponding to the user command. In this case, the preset control quantity may be a steering angle that is necessary for the vehicle 100 to perform a lane change maneuver.

If a user command for steering is received and a determination is made to apply the user command, the controller 170 may control the vehicle 100 to perform lane changing, make a left-turn, or make a right turn in a direction corresponding to the user command.

For example, when applying a user command for turning a steering direction to the right, the controller 170 may control the vehicle 100 to move into the right-hand lane or make a right-turn, regardless of a steering angle corresponding to the user command. In this case, the controller 170 may perform a lane change maneuver when there is a lane on the right side of the vehicle 100, or may make a right turn when the vehicle 100 is travelling in the rightmost lane.

If a user command for acceleration is received and it is determined to apply the user command, the controller 170 may increase a speed of the vehicle 100 by a preset amount of acceleration. If a user command for deceleration is received and it is determined to apply the user command, the controller 170 may reduce a speed of the vehicle 100 by a preset amount of deceleration.

For example, when applying a user command for acceleration or deceleration, the controller 170 may change a speed of the vehicle 100 based on a preset speed variation, regardless of a speed variation corresponding to the user command. Accordingly, if a driver presses an accelerator pedal, the controller 170 may increase a speed of the vehicle 100 by a preset value, regardless of the depth to which the accelerator pedal is pressed.

In some implementations, if a user command is received, the controller 170 may calculate a control limit corresponding to the user command based on vehicle driving information. In this case, the controller 170 may control the vehicle 100 based on the vehicle driving information, the user command, and the control limit.

A control limit may indicate the extent to which the vehicle 100 can be controlled based on a user command. For example, a control limit with regard to steering of the vehicle 100 may be right 45 degrees. In this case, although a user command for turning a steering direction of the vehicle 100 at 45 degrees or greater to the right is received, the controller 170 may turn a steering direction of the vehicle 100 up to by 45 degrees to the right.

FIGS. 14A and 14B illustrate an example vehicle that determines a control limit to apply a user command.

Referring to FIG. 14A, if a user command for steering is received, the controller 170 may calculate a steering control limit 141 b of the vehicle 100. The steering control limit 141 b may be a maximum angle at which a steering direction of the vehicle 100 can be turned.

For example, if a user command for steering is received, the controller 170 may determine a speed of the vehicle 100 based on vehicle driving information. Based on speed information of the vehicle 100 and road surface state information, which are included in the vehicle driving information, the controller 170 may calculate a maximum steering angle which does not cause the vehicle 100 to slip. In this case, the maximum steering angle may be referred to as a steering control limit.

Based on the steering control limit 141b, the controller 170 may apply the user command for steering.

For example, when it is determined that a speed of the vehicle 100 is 100 km/h, the vehicle 100 is highly likely to slip by a slight steering variation. Thus, the controller 170 may apply a steering angle 141a corresponding to a user command within the steering control limit 141 b. Accordingly, if the steering angle 141 a corresponding to a user command is greater than the steering control limit 141 b, the controller 170 may control the vehicle 100 to turn a steering direction according to the steering control limit 141 b. On contrary, if a steering angle corresponding to a user command is equal to or smaller than the steering control limit 141 b, the controller 170 may control the vehicle 100 to turn a steering direction according to the steering angle corresponding to the user command. In this case, the steering angle of the vehicle 100 may be adjusted in proportion of the steering angle corresponding to the user command.

Referring to FIG. 14B, if a user command for acceleration is received, the controller 170 may calculate an acceleration control limit based on vehicle driving information. For example, the controller 170 may calculate a safety distance 142 c between the vehicle 100 and a nearby vehicle 142 d ahead of the vehicle 100 based on vehicle driving information. If a user command for acceleration is received, the controller 170 may calculate an acceleration control limit 142 b based on the calculated safety distance 142 c.

Based on the acceleration control limit, the controller 170 may apply the user command.

For example, if a control quantity 142 a corresponding to a user command is greater than the acceleration control limit 142 b, the controller 170 may control a speed of the vehicle 100 to correspond to the acceleration control limit 142 b. On contrary, if a control quantity corresponding to a user command is equal to or smaller than the acceleration control limit 142 b, the controller 170 may control a speed of the vehicle 100 to correspond to the control quantity corresponding to the user command.

If a user command for deceleration is received, the controller 170 may calculate a deceleration control limit of the vehicle 100 based on vehicle driving information. Then, based on the deceleration control limit, the controller 170 may apply the user command.

In some implementations, the controller 170 may limit a degree of manipulation by the driving manipulation device 500 according to a control limit.

The driving manipulation device 500 may include: a steering wheel which receives a user command for steering; an acceleration pedal which receives a user command for acceleration; and a brake pedal which receives a user command for deceleration.

If a user command for steering is received, the controller 170 may control a steering wheel based on a steering control limit so as to limit an angle of rotation of the steering wheel.

The controller 170, based on the steering control limit, block the steering wheel from turning more than a first angle. The first angle is an angle corresponding to the steering control limit.

For example, in the case shown in FIG. 14A, the controller 170 may control the steering wheel to be rotated up to an angle 141 b corresponding to a calculated steering control limit. In this case, the steering wheel cannot be turned beyond the angle 141 b corresponding to the steering control limit. The angle 141 b is the first angle.

If a user command for acceleration is received, the controller 170 may control an accelerator pedal based on an acceleration control limit so as to limit a depth up to which the accelerator pedal can be pressed.

The controller 170, based on the acceleration control limit, block the accelerator pedal from being pressed more than a first depth.

The first depth is the maximum depth at which the accelerator pedal can be depressed corresponding to the acceleration control limit.

If a user command for deceleration is received, the controller 170 may control a brake pedal based on a deceleration control limit so as to limit a depth up to which the brake pedal can be pressed.

The controller 170, based on the deceleration control limit, block the brake pedal from being pressed more than a second depth.

The second depth is the maximum depth at which the brake pedal can be depressed corresponding to the deceleration control limit.

For example, in the case shown in FIG. 14B, the controller 170 may control the accelerator pedal to be pressed to a depth corresponding to the acceleration control limit 142 b. In this case, the first depth is the depth corresponding to the acceleration control limit 142 b. The accelerator pedal cannot be pressed beyond the depth corresponding to the acceleration control limit 142 b.

FIG. 15 illustrates an example vehicle that outputs a control limit and a control result.

Referring to the example (a) in FIG. 15, if a user command for steering is received, the controller 170 may output a steering control limit and a result of steering control of the vehicle 100.

If a user command for steering is received, the controller 170 may determine a speed of the vehicle 100 based on vehicle driving information. Based on the speed information of the vehicle 100 and road surface state information, which are included in the vehicle driving information, the controller 170 may calculate a maximum steering angle which does not cause the vehicle 100 to slip.

The controller 170 may output a path to travel based on a user command, and a path to travel in accordance a steering control limit. If a windshield of the vehicle 100 has a transparent display, the controller 170 may display the above two paths on the wind shield. The controller 170 may display the two paths in augmented reality (AR). If a steering angle corresponding to the user command is greater than the steering control limit, a steering angle of the vehicle 100 is controlled according to the steering control limit, and thus, the steering control limit which is identical to a result of steering control of the vehicle 100 may be displayed.

The controller 170 may display, on the wind shield, a path to travel based on the user command.

Referring to the example (b) in FIG. 15, if a user command for acceleration is received, the controller 170 may output an acceleration control limit and a result of speed control of the vehicle 100. If a user command for deceleration is received, the controller 170 may output a deceleration control limit and a result of speed control of the vehicle 100.

The result of speed control of the vehicle 100 based on the user command for acceleration, or the result of speed control of the vehicle 100 based on the user command for deceleration may be the current travelling speed 150 a of the vehicle 100.

For example, the controller 170 may display the current speed 150 a, an acceleration control limit 150 b, and a deceleration control limit 150 c on the display unit 251 that is provided additionally.

FIG. 16 illustrates an example autonomous vehicle that determines a location to which the vehicle moves.

If it is determined that a user command is inconsistent with vehicle driving information, the controller 170 may determine, based on the user command and the vehicle driving information, a location at which the user command is applicable.

The controller 170, in a state in which the user command is inconsistent with the vehicle driving information, determines a first location at which the user command is applicable.

The first location is a position where the user command and the vehicle driving information may consistent. The controller 170, moves the vehicle to the first location.

The controller 170, controls the vehicle based on the user command and the vehicle driving information.

The controller 170 may move the vehicle 100 to the determined location, and control the vehicle 100 based on the user command and the vehicle driving information.

Referring to FIG. 16, if a user command for lane change is received through an input device and it is determined, based on vehicle driving information, that the vehicle 100 is now not allowed to perform a lane change maneuver, the controller 170 may move the vehicle 100 to a location at which the vehicle 100 is able to perform the lane change maneuver. Then, the controller 170 may control the vehicle 100 based on the user command and the vehicle driving information to perform a lane change maneuver.

The controller 170, in a state in which the input device receives the user command including a user command for lane change, determines, based on the vehicle driving information, whether the user command for changing lanes is applicable.

The controller 170, in a state in which the user command for changing lanes is not applicable, determines a second location at which the user command for changing lanes is applicable.

The second location is a position on the basis of the vehicle driving information, which is determined to be a position at which the vehicle can perform lane change according to a user command.

The controller 170, based on the vehicle driving information, determines the second location where the vehicle 100 is able to perform a lane change maneuver.

The controller 170, moves the vehicle to the second location.

The controller 170, based on the user command and the vehicle driving information, controls the vehicle to change lanes.

If a user command for moving the vehicle 100 into the right-hand lane is received, the controller 170 may determine whether to apply the user command based on vehicle driving information. If it is determined, based on the vehicle driving information, that a nearby vehicle 160a exists in the right-hand lane, the controller 170 may determine that the user command is inconsistent with the vehicle driving information, and thus determine to ignore the user command.

If the vehicle 100 is ahead or behind the nearby vehicle 160 a, the vehicle 100 is able to move into the right-hand lane.

Based on vehicle driving information, the controller 170 may determine a location at which the vehicle 100 is able to perform a lane change maneuver.

Based on vehicle driving information, the controller 170 may determine that the position that is away from the nearby vehicle 160 a by a first reference distance or more in a traveling lane on which the vehicle 100 travels is the second location. The first reference distance is a reference value for determining the second location.

In the example (a), the controller 170 may accelerate the vehicle 100, so that the vehicle 100 moves to a location at which the vehicle 100 is able to move into the right-hand lane. The controller 170 may control the vehicle 100 to be located a predetermined distance or more ahead of the nearby vehicle 160 a and then move into the right-hand lane.

In the example (b), the controller 170 may decelerate the vehicle 100, so that the vehicle 100 moves into a location at which the vehicle 100 is able to move into the right-hand lane. The controller 170 may control the vehicle 100 to be located a predetermined distance or more behind the nearby vehicle 160 a and then move into the right-hand lane.

FIGS. 17A and 17B illustrate another example autonomous vehicle that determines a location to which the vehicle moves.

Referring to FIG. 17A, if a user command for acceleration is received through an input device and it is determined, based on vehicle driving information, that the vehicle 100 is now not allowed to accelerate, the controller 170 may move the vehicle 100 into a lane in which the vehicle 100 is able to accelerate. Then, based on the user command for acceleration and the vehicle driving information, the controller 170 may control the vehicle 100 to accelerate.

The controller 170, in a state in which the input device receives the user command including the user command for acceleration, determines, based on the vehicle driving information, whether the user command for acceleration is applicable.

The controller 170, in a state in which the user command for acceleration is not applicable, determines a third location at which the user command for acceleration is applicable.

The third location is a position on the basis of the vehicle driving information, which is determined to be a position at which the vehicle can perform acceleration according to a user command.

The controller 170, based on the vehicle driving information, determines the third location where the vehicle 100 is able to perform acceleration according to a user command.

The controller 170 moves the vehicle to the third location.

The controller 170, based on the user command for acceleration and the vehicle driving information, controls the vehicle to accelerate.

If it is determined, based on vehicle driving information, that a nearby vehicle 170a exists within a safety distance from the vehicle 100, the controller 170 may determine that the vehicle 100 is now not allowed to accelerate. If a user command for acceleration is received, the controller 170 may determine that the user command is inconsistent with the vehicle driving information. The controller 170 may ignore the user command for acceleration.

If it is determined, based on vehicle driving information, that a nearby vehicle does not exists in the right-hand lane and that the vehicle 100 is now able to accelerate in the right-hand lane, the controller 170 may determine that the right-hand lane is a location at which the user command is applicable. The controller 170 determines the right-hand lane as the third position.

The controller 170 may move the vehicle 100 into the right-hand lane.

After moving the vehicle 100 into the right-hand lane, the controller 170 may control the vehicle 100 by applying the user command for acceleration.

Referring to FIG. 17B, if a user command for deceleration is received through an input device and it is determined, based on vehicle driving information, that the vehicle 100 is now not allowed to decelerate, the controller 170 may move the vehicle 100 into a lane in which the vehicle 100 is able to decelerate. Then, based on the user command for deceleration and the vehicle driving information, the controller 170 may control the vehicle 100 to decelerate.

The controller 170, in a state in which the input device receives the user command including a user command for deceleration, determines, based on the vehicle driving information, whether user command for deceleration is applicable.

The controller 170, in a state in which the user command for deceleration is not applicable, determines a fourth location at which the user command for deceleration is applicable.

The fourth location is a position on the basis of the vehicle driving information, which is determined to be a position at which the vehicle can perform deceleration according to the user command.

The controller 170, based on the vehicle driving information, determines the fourth location where the vehicle 100 is able to perform deceleration according to the user command.

The controller 170, moves the vehicle to the fourth location.

The controller 170, based on the user command for deceleration and the vehicle driving information, controls the vehicle to decelerate.

If it is determined, based on vehicle driving information, that a nearby vehicle 170 b is travelling within a safety distance behind the vehicle 100, the controller 170 may determine that the vehicle 100 is now not allowed to decelerate. In this case, if a user command for deceleration is received, the controller 170 may determine that the user command is inconsistent with the vehicle driving information. Accordingly, the controller 170 may ignore the user command for deceleration.

If it is determined, based on vehicle driving information, that a nearby vehicle does not exist in the right-hand lane and that the vehicle 100 is now able to decelerate in the right-hand lane, the controller 170 may determine that the right-hand lane is a location at which the user command is applicable. The controller 170 determines the right-hand lane as the fourth position.

The controller 170 may move the vehicle 100 to the right-hand lane.

After moving the vehicle 100 to the right-hand lane, the controller 170 may control the vehicle 100 by applying the user command for deceleration.

in some implementations, the controller 170 may determine whether a user command received through the driving manipulation device 500 and a user command received through the input unit 210 both correspond to vehicle driving information, and then determine whether to apply the user commands based on the determination.

For example, the controller 170 may receive, through the input unit 210, a user command for switching a control mode of the vehicle 100, a user command for changing a preset path, and a user command for activating any of various devices provided in the vehicle 100. For example, during autonomous travelling of the vehicle 100, the controller 170 may receive, through the input unit 210, a user command that requests a manual driving mode.

For example, the controller 170, in a state in which the vehicle is travelling at an autonomous driving mode, determines whether the input device receives the user command including a user command switching to a manual driving mode.

The controller 170, based on a determination that the input device receives the user command switching to the manual driving mode, determine a fifth location at which the manual driving mode is available.

the fifth location is a position on the basis of the vehicle driving information, which is determined to be a position at which the vehicle can switch to the manual driving mode according to the user command.

The controller 170, based on the vehicle driving information, determines the fifth location where the vehicle 100 is able to switch to the manual driving mode according to the user command.

The controller 170, move the vehicle to the fifth location.

For example, if a user command corresponding to a request for a manual driving mode of the vehicle 100 is received and it is determined, based on vehicle driving information, that the vehicle 100 is travelling in an autonomous driving road, the controller 170 may control the vehicle 100 to move into a lane where manual driving is allowed.

If it is determined that the vehicle 100 is travelling on an autonomous driving road or if it is determined that a user command requesting for a manual driving mode is received, the controller 170 may determine that a user command is inconsistent with vehicle driving information.

In this case, a location at which the user command is applicable may be a manual driving road on which a driver is allowed to drive the vehicle 100. The manual driving road is the fifth location.

The controller 170 may determine a location of the manual driving road based on map information included in navigation information, and may control the vehicle 100 to move to the determined location of the manual driving road.

After the vehicle 100 moves to the manual driving road, the controller 170 may switch the vehicle 100 to a manual driving mode based on the user command.

FIG. 18 illustrates an example user interface of an autonomous vehicle to get user's confirmation for moving to a particular location.

If it is determined that a user command is inconsistent with vehicle driving information, the controller 170 may output a notification and a menu to the display unit 250. The notification indicates that the vehicle 100 is now not allowed to apply the user command, and the menu is to get a confirmation from a user as to whether the user wants to move the vehicle 100 to a location at which the user command is applicable.

The controller 170 may output the notification and the menu to at least one of the display unit 251 and the sound output unit 252. The notification and the menu may be output in the form of audio guide that is output via the display unit 251. Hereinafter, the following description is described in the assumption that the notification and the menu is output through the display unit 251.

In the example (a), if a user command for changing a lane is received and it is determined, based on vehicle driving information, that the vehicle 100 is now not allowed to perform a lane change maneuver, the controller 170 may determine that the user command is inconsistent with the vehicle driving information. In this case, the controller 170 may display, on the display unit 251, a notification 180 a which indicates that the vehicle 100 is now not allowed to perform a lane change maneuver in accordance to the user command. The controller 170 may display, on the display unit 251, a menu 180 b to confirm whether to move the vehicle 100 to a location at which the lane change maneuver is possible to be performed. The controller 170 may include buttons in the menu 180 b to receive the user′ response responsive to the menu 180 b.

If a user's response to the menu 180 b is received and indicates the intention to move into a location at which the user command is applicable, or if a user command continues to be received for a preset period of time or more, the controller 170 may move the vehicle 100 into a determined location. The preset period of time is a value stored in the memory 140, which may be set by a user. For example, the preset period of time may be two seconds.

The controller 170, in a state in which the user command is inconsistent with the vehicle driving information, provides, to the output unit, (i) a notification indicating that the user command is not applicable and (ii) a menu to receive a confirmation, from the user, as to whether the user intends to move the vehicle to the first location at which the user command is applicable.

The first location is a position where the user command and the vehicle driving information may consistent.

The controller 170, (i) in response to the confirmation that the user intends to move the vehicle to the first location or (ii) in a state in which the input device receives two or more user commands that are inconsistent with the vehicle driving information for a first time period, moves the vehicle to the first location.

The first time is the preset period of time.

In the example (a), if a user's selection of YES button in the menu 180 b is received, the controller 170 may determine that the user's response is received and indicates the intention to move the vehicle 100 to a location at which the vehicle 100 is able to perform a lane change maneuver in accordance to a user command. In this case, the controller 170 may move the vehicle 100 to the location at which the vehicle 100 is able to perform the lane change maneuver. If a user's selection of No button in the menu 180 b is received or if a user command for lane change continues to be received for a preset period of time or more, the controller 170 may control the vehicle 100 based solely on vehicle driving information, without moving the vehicle 100 to the location at which the vehicle 100 is able to perform the lane change maneuver.

In the example (b), if a user command for acceleration of the vehicle 100 is received and it is determined, based on vehicle driving information, the vehicle 100 is now not allowed to accelerate, the controller 170 may determine that the user command is inconsistent with the vehicle driving information. In this case, the controller 170 may display, on the display unit 251, a notification message 180 a which indicates that the vehicle 100 is now not allowed to accelerate based on the user command. The control unit 170 may display, on the display unit 251, a menu 180 b to confirm whether to move the vehicle 100 to a location at which the vehicle 100 is able to acceleration.

If a user's selection of Yes button is received responsive to the menu 180 b, the controller 170 may determine that a user input is received and indicates the intention to move the vehicle 100 to a location at which the vehicle 100 is able to accelerate based on the user command. In this case, the controller 170 may move the vehicle 100 to the location at which the vehicle 100 is able to accelerate. If a user's selection of No button is received responsive to the menu 180 b or if a user command for acceleration continues to be received for a preset period of time or more, the controller 170 may control the vehicle 100 based solely on vehicle driving information, without moving the vehicle 100 to the location at which the vehicle 100 is able to accelerate.

In some implementations, if a user command inconsistent with vehicle driving information is received for a preset period of time or more, the controller 170 may control the vehicle 100 to perform a preset operation associated with the user command. The preset period of time is a value stored in the memory 140, which may be set by a user. For example, the preset period of time may be three seconds. The preset operation may be an operation that the vehicle 100 performs in response to a particular user command. The preset operation may be changed by the user. A control command corresponding to the preset operation may be stored in the memory 140. The preset period of time is a second time period.

The controller 170, in a state in which the input device receives two or more user commands that are inconsistent with the vehicle driving information for the second time period, controls the vehicle to perform the preset operation associated with the user command.

For example, if a user command for deceleration continues to be received for a set period of time or more when it is determined, based on vehicle driving information, that the vehicle 100 is now not allowed to decelerate, the controller 170 may control the vehicle 100 to perform emergency stop. For example, emergency stop is an operation of stopping the vehicle 100 temporarily in any available location in the vicinity. In this case, the controller 170 may determine, based on vehicle driving information, an available stopping location closest to the vehicle 100, and then move the vehicle 100 to the determined location. During the emergency stop maneuver, the controller 170 may display a notification message indicative of emergency stop on a display device provided outside the vehicle 100, or may inform a nearby vehicle or road infrastructure that the vehicle 100 is performing emergency stop.

The controller 170 determines whether the input device receives two or more user commands for deceleration for the second time period, the two or more user commands for deceleration being inconsistent with the vehicle driving information.

The controller 170, based on a determination that the input device receives the two or more user commands for deceleration for the second time period, control the vehicle to perform emergency stop.

For example, if it is determined, based on vehicle driving information, that the vehicle 100 is travelling on highways and that a nearby vehicle is travelling behind the vehicle 100, the controller 170 may determine that the vehicle 100 is now not allowed to decelerate. In this case, if a driver presses a brake pedal for three seconds or more, the controller 170 may control the vehicle 100 to perform emergency stop.

For example, if a user command for acceleration continues to be received for a preset period of time or more when it is determined, based on vehicle driving information, that the vehicle 100 is now not allowed to accelerate, the controller 170 may control the vehicle 100 to enter an acceleration mode. The acceleration mode may be a mode in which the vehicle 100 overtakes a nearby vehicle or searches for a lane or path of smooth traffic flow in order to travel at a preset speed.

The controller 170 determines whether the input device receives two or more user commands for acceleration for the second time period, the two or more user commands for acceleration being inconsistent with the vehicle driving information.

The controller 170, based on a determination that the input device receives the two or more user commands for acceleration for the second time period, accelerate the vehicle.

In some implementations, if a user command is received, the controller 170 may output, to the output unit 250, determination as to whether to apply the user command. For example, if a user command is received during autonomous travelling of the vehicle 100, the controller 170 may determine whether to apply the user command, based on the received user command and vehicle driving information, and then display the determination on the display unit 251. Accordingly, a driver of the vehicle 100 may be able to know whether a command input by himself is applicable, and even the reason when the command is not applicable.

In some implementations, the controller 170 determines whether to apply one or more user commands, received through an input device, individually, and may stop applying the user commands individually based on vehicle driving information.

The fact that the controller 170 stops applying a user command indicates that the controller 170, which was controlling the vehicle 100 based on vehicle driving information along with the user command, starts to control the vehicle 100 based solely on the vehicle driving information without the user command. That is, stopping applying the user command includes stopping controlling the vehicle 100 based on the user command and starting to control the vehicle 100 based solely on the vehicle command.

While controlling the vehicle 100 based on a user command and vehicle driving information, the controller 170 may stop applying the user command when it is determined that the user command is inconsistent with the vehicle driving information.

For example, while the vehicle 100 is controlled based on one or more user commands and vehicle driving information in response to determination to apply the user commands, the controller 170 may determine whether at least one of the user commands is inconsistent with the vehicle driving information. When the vehicle 100 is travelling autonomously, surrounding environment of the vehicle 100 and information received via the communication device 400 may be changed. As a result, the vehicle driving information may be changed. Therefore, even a user command which was consistent with previous vehicle driving information may be determined inconsistent with the current vehicle driving information.

If it is determined that at least one user command which is now being applied is inconsistent with vehicle driving information, the controller 170 may stop applying the at least one user command. For example, if it is determined that the vehicle 100 is crossing the centerline based on vehicle driving information while the vehicle 100 is controlled to turn a steering direction based on a user command for steering, which is determined consistent with vehicle driving information, the controller 170 may ignore the user command and control the vehicle 100 not to cross the centerline. For example, if it is determined that a probability of collision with an ahead object will increase to more than a preset value based on vehicle driving information while the vehicle 100 is controlled to increase a travelling speed based on a user command, the controller 170 may ignore the user command and control the vehicle 100 to decelerate. The preset value may be determined through experiments. For example, while the vehicle 100 is controlled to turn a steering direction while accelerating based on a user command for acceleration and a user command for steering, the controller 170 may determine, based on vehicle driving information, to stop turning the steering direction so as to prevent the vehicle 100 from slipping, so that the vehicle 100 may keep accelerating without slipping.
